Hybrid pumped laser sources based hybrid traveling wave SOA and optical EDFA amplifies for signal quality improvement

Abstract

Abstract This paper has demonstrated the hybrid pumped laser sources based hybrid traveling wave SOA and optical EDFA amplifies for the signal quality improvement. The previous effective noise figure and fiber loss variations are clarified against wavelength band with/without amplification. The related previous signal output power versus Raman/EDFA pumped amplification and signal power conversion efficiency are indicated versus the launched pump power with the Raman/EDFA pumped amplification. The signal quality factor/BER against the transmission distance with/without amplification after receiver side. The modified amplified light signal power is demonstrated after 300 km distance SMF channel with wavelength band variations. The modified amplified light signal power is clarified after 300 km distance SMF channel by using optical power meter. The modified amplified light signal power is clarified after 300 km distance SMF channel with time band variations. The modified amplified electrical signal power is demonstrated after 350 km distance SMF channel with frequency band variations. The modified amplified electrical signal power is clarified after 350 km distance SMF channel with time band variations. The modified amplified electrical signal power is demonstrated after 350 km distance SMF channel by using electrical power meter.
